As requested in: #777
Adding the
ServiceBuilder::boxed_clone_sync()
method to matchboxed_clone
andboxed()
.Note that in this case, I used the named,
BoxCloneSyncServiceLayer
, rather than the layer fn returned byBoxedCloneSyncService::layer()
. I don't really see a good reason to prefer the latter. I think the reason that other helpers use that, is historical (named layer didn't exist yet).Probably we should migrate everything over, but that seems likely to be a breaking change so I held off. Glad to cut an issue on that if you concur.
The only testing was via a doctest. This matches the other helper.
